IMPROVEMENT IN CAR-COUPLINGS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern Be itknown that I, JOHN COLEMAN, ofLynchburg, in the county of Campbell and State of Virginia, haveinvented a new and improved (Jar-Coupler; and I do hereby declare thatthe following is a full, clear, and 'ekact'description of the same,reference beiu g had to the accompanying drawings making a part of thisspecification, in which- Figure 1 is a sectional elevation, and

Figure 2 is a plan view.

This invention consists in the combiuatioi-i with a bumper, openatthesides, of a hingeddetentarranged within the bumper so 'as to allowthe head of the coupling-bar to pass under it, and then to fall by itsown-weight upon the body of ,the bar, and retain it, and of a.coupling-link, having beveled heads which pass easily under the detents,against the inner sides of which heads the free ends of the detentsbear, the coupling being automatic and universal in its applicatiou.

In the drawings- A A-are the bumpers, open at the sides, and havingrecesses, a, cut through their upper branches, in which recesses thedeteuts b are hung by pivots passing through their upper ends.

Each detent rests on an inclined shelf, 0, extending across thefro'ntpart of the draw-head, so that the (letents incline backward, andhence present no obstacle but their weight to throw the running of thebeveled heads d d of the coupling-link 2 under them.

As soon as the head cl has passed under the free end of the detent, thelatter falls on the body of. the

'ineans except the uplifting of the detent.

link, and prevents the withdrawal at the latter by any But, in case ofthe running of one car otf the track, there is nothing to prevent such alateral movementof the link as shall draw the head d out at the openside of the bumper, and uncouple the displaced car from those stillremaining on the track. The rounding of the inner sides of the heads dfacilitates this operation.

The detents b are so heavy that one of them will hold the linkhorizontal, so as to din-mt it straight to the bumper of the nextadjacent car in coupling.

Hence, this coupling is automatic.

Passages, It 7:, are made longitudinally through the rear parts of thebumpers, and, also, vertical orifices, in which pins, '6 '5, are placed,by which to make the ordinary coupling-link serve when none of the links6 are at hand.

Vertical slots, k 7;, near the ends of each link e, may be used toreceive the pins i when-the detents b are out of order, or when theordinary draw-heads are used.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the bumper A, having open sides,\vitli the detent I)and link 0, in the manner and for the purpose set forth.

JOHN COLEMAN.
